Cannot delete virus, it has locked me out

[Lee2k4]

Been having a hell of a time these past few weeks trying to get rid of these viruses, scanned with various on-line scanners which found 4 and AVAST can't delete them because it gives me this. I have not locked or passworded any files so what the hell is it saying that for?

Get urself a copy of HiJackThis (www.merijn.org) install it and create a log file.

Now post the log file contents at a recognised security forum or the one in my sig.
